Monocyte chemotactic protein-1 as a potential biomarker for early anti-thrombotic therapy after ischemic stroke.

Inflammation following ischemic brain injury is correlated with adverse outcome. Preclinical studies indicate that treatment with acetylsalicylic acid + extended-release dipyridamole (ASA + ER-DP) has anti-inflammatory and thereby neuroprotective effects by inhibition of monocyte chemotactic protein-1 (MCP-1) expression. We hypothesized that early treatment with ASA + ER-DP will reduce levels of MCP-1 also in patients with ischemic stroke.

Dipyridamole in antithrombotic treatment.

The antithrombotic activity of dipyridamole was initially discovered in an in vivo experiment about half a century ago. At that time science had not appreciated the complexity of the regulation of local thrombus formation. Inhibition of platelets has been the main focus for the prevention of arterial thrombus formation.

Dabigatran: an oral novel potent reversible nonpeptide inhibitor of thrombin.

Dabigatran is a highly selective, reversible, and potent thrombin inhibitor and is orally available as the prodrug, dabigatran etexilate. It has shown antithrombotic efficacy in animal models of thrombosis, with a rapid onset of action and predictable pharmacodynamic response. Peak plasma concentrations of dabigatran occur 1 to 2 hours after ingestion of the prodrug.

Accumulation of radiolabelled platelets and fibrin on the carotid artery of rabbits after angioplasty: effects of heparin and dipyridamole.

We investigated the dynamic accumulation of platelets and fibrin after balloon injury of the carotid arteries in rabbits in vivo. In addition, effects of heparin and dipyridamole treatment were also tested. Autologous (99m)Tc-labelled platelet and (123)I-labelled fibrin accumulation was measured at one minute intervals for 4 hours following balloon injury of the carotid artery.
